    Albemarle idles Kemerton lithium hydroxide plant: supply and capex lens for mine planners

    Albemarle idles Kemerton lithium hydroxide plant: supply and capex lens for mine planners

    First reported on MINING.com

    30 Second Briefing

    Albemarle is idling the last operating train at its Kemerton lithium hydroxide plant in Western Australia and placing the facility into care and maintenance immediately, after already mothballing Train 2 in 2024 and cancelling expansion of Trains 3 and 4. The Kemerton refinery converts spodumene feed from the Greenbushes hard-rock mine, where Albemarle holds both equity and 50% of offtake rights, into battery-grade lithium hydroxide for a Western supply chain. Albemarle expects the shutdown to be accretive to adjusted EBITDA from Q2 2026, with 2026 lithium hydroxide volumes backfilled from other global plants.

    Technical Brief

    • Train 2 had already been placed into care and maintenance during 2024, reducing conversion redundancy.
    • Expansion halt for Trains 3 and 4 removes planned incremental hydroxide conversion capacity at Kemerton.
    • Mining interests at Greenbushes and Wodgina, and WA exploration tenements, remain operational and “core” to strategy.
    • CEO attributes the decision to extended lithium price volatility and cost pressure on Western hard-rock converters.

    Our Take

    Albemarle’s role in Chilean R&D on direct lithium extraction and rare earth recovery, as noted in the Corfo-backed project from January 2026, signals that while Kemerton in Western Australia is being idled, the company is still allocating capital and technical effort toward next-generation lithium processing routes elsewhere.

    Within our mining database, lithium and lithium hydroxide items are a relatively small subset compared with bulk commodities, so a major processing pause in Western Australia stands out as one of the more consequential operational shifts in the battery-materials space rather than just another project delay.

    The decision to target adjusted EBITDA accretion from Kemerton changes by the second quarter of 2026 suggests Albemarle is aligning Australian processing capacity with a medium-term price and demand recovery window, which operators at upstream assets like Greenbushes and Wodgina will need to factor into their own expansion and offtake planning.

    Focus Graphite’s Lac Tetepisca resource: capex and pit geometry notes for engineers

    Focus Graphite’s Lac Tetepisca project in central Quebec now hosts 14.7 million tonnes of contained graphite at 10.2% Cg, an 86% increase over its 2022 resource, ranking fifth globally and second in North America by contained tonnes. The updated estimate, based on 26,095 metres of drilling in 150 holes, includes 12.3 million tonnes contained graphite in measured and indicated resources (120.1 million tonnes at 10.27% Cg) plus 2.3 million tonnes inferred (24.1 million tonnes at 9.88% Cg). Grades above 10% Cg, open-pit geometry with favourable strip ratios, low-cost Quebec hydropower and planned >99.9% purity processing underpin analyst views that Focus trades at an 81% discount to peers.

    Freeport’s delayed Grasberg restart to 2028: production and risk notes for mine engineers

    Freeport Indonesia has pushed back Grasberg’s full production restart to early 2028, after a September mudflow in the Grasberg Block Cave killed seven workers, halted underground mining and triggered force majeure on shipments. The complex, which previously supplied about 3% of global copper (1.7 billion lb/year) and 1.4 million oz/year of gold, is currently operating at roughly 40–50% capacity, with copper output for 2026 now guided at 700 million lb versus a prior 1‑billion‑lb target. Ramp-up targets have been reset to 65% capacity in H2 2026 and 80% by mid‑2027, as additional logistics and ore-handling infrastructure work proceeds.

    San Lorenzo Chile gold assays: porphyry potential and drilling cues for mine planners

    San Lorenzo Gold’s Salvadora project in Chile’s Atacama region returned strong gold intercepts at the Arco de Oro target, with hole SAL-10-25 cutting 102 m at 1.33 g/t Au from 153 m (including 13 m at 2.21 g/t), and nearby SAL-09-25 yielding 59 m at 1.07 g/t Au from 238 m (including 11 m at 3.78 g/t). Exploration VP Terence Walker interprets the results as the upper levels of a gold‑rich porphyry Cu‑Au system, open in all directions and warranting immediate follow‑up drilling. The 90+ sq. km Salvadora property lies about 15 km from Codelco’s El Salvador mine, and a C$20 million March placement is funding ongoing step‑out drilling across five porphyry and epithermal targets.
